Grumbacher Damar Retouch Varnish

Grumbacher Damar Retouch Varnish is a spray damar varnish for use during intermediate stages of development in an oil painting to even out the gloss of unfinished works, or to revive sunken in or dry areas to aid in accurate color comparison for further painting.

Grumbacher Damar Retouch Varnish can also be used to protect paintings before final varnishing. Transparent, quick-drying, clear, and glossy, it must be allowed to dry completely before overpainting. When the surface of the painting is dry to the touch, one very light coat of Retouch may be applied to it for protection against excessive dust.

Use Grumbacher Damar Retouch Varnish only in thin layers. If the coat produces a gloss, too much has been applied.

I spray this on our oil paintings to enhance it and it works great. It is easy to use. Just shake and spray. The drawback as any other spray cans is that it hurts my finger after prolonged use. In any case it is a great product.
